A 19-year-old Steelton man has been charged with statutory sexual assault and related charges for allegedly having sex with a 13-year-old West York girl he met online.

Muhammad Shahab, of the 400 block of North Front Street, met the girl through an app called MeetMe -- advertised with the slogan "Meeting the universal need for human connection" -- and chatted with her on Facebook before going to her West York home to meet her on May 6.

Online, according to a criminal complaint filed in the case, Shahab identified himself as "Alex" and said he was 19. The girl's profile on the app listed her age as 13, the complaint states.

The complaint states that Shahab came to her home that Sunday and had sex with her. The girl told a forensic interviewer that her mother's boyfriend knew that "Alex" was coming to the house to have sex with her and that she let her mother's boyfriend read the text messages between her and Shahab.

After, she told the interviewer, she told her mother's boyfriend "everything about it." She and her mother's boyfriend spoke about "not letting this get out and not (getting) anyone into trouble."

The police arrived at her home a short time later. The complaint does not specify who called the police.

During her first interview with investigators, according to the complaint, the girl did not tell them that she had sex with Shahab. In a second interview, however, the girl said that Shahab did have sex with her.

Specifically, Shahab is charged with committing involuntary deviate sexual intercourse with a person under 16, unlawful contact with a minor, statutory sexual assault, corruption of minors and other charges.
